Living Through Cell Phones In case you haven’t noticed, we live in a cell phone-centric world. Steve Largent, president and CEO of the CTIA said at one of the keynotes during the recent conference, “We are living through our cell phones”. At first I was skeptical of such a statement, but thinking about it, he’s right. — Louis E. Frenzel March 10, 2008 60 GHz Of Promise Land . . . Or Is It? Each week I hear more about products and plans for the unlicensed 60 GHz spectrum. Yes, that is 60 gigaHertz, or 60 billion cycles per second. Very high frequency indeed. What can you do with frequencies that high? Well, with all the progress in 60 GHz semiconductors, we are about to find out. A 60 GHz wireless product is probably in the near future. — Louis E. Frenzel February 11, 2008 Antennas: The Black Art Of Wireless The theory is well known and the design/simulation software is better than ever, but antenna design seems to thrive on intuition, a bit of art and some believe actual magic, and lots of experimentation. — Louis E. Frenzel January 2, 2008 What’s Happening In Short-Range Wireless? There are literally dozens of methods used in transmitting data wirelessly over short distances. Here is a look at what is happening with some of the more commonly used standards like Wi-Fi, Bluetooth, UWB and ZigBee. — Louis E. Frenzel November 28, 2007 Will Google And Femtos Reshape The Wireless Industry? There are a couple of subjects I never got around to this year in WSD, specifically the Google cell phone possibilities and femto cell’s potential. None of this exists at the moment except for some trials here and there, but you will be hearing more about them in the coming year. Here is a look at what to expect. — Louis E. Frenzel November 5, 2007 The Cell Phone: Best Wireless Product Ever Or Menace? Have you become dependent on your cell phone? Do you feel naked without it? Has your cell phone become a source of entertainment as well as just a way to make a phone call? Most of you would say yes to all those questions. Which is why the cell phone business has grown so big and continues to get bigger. — Louis E. Frenzel October 3, 2007 Sputnik: Golden Anniversary It was 50 years ago October 4th that the first successful satellite was put into orbit. Launched by the Russians, this satellite called Sputnik, as basic as it was, set off a stream of events that could not have been anticipated. Besides starting the space race, launching the satellite industry, revolutionizing the telecommunications business, and intensifying the cold war, this satellite had so many unintended consequences, good and bad, it is hard to identify all of them. — Louis E. Frenzel September 6, 2007 $200 MILLION PER MEGAHERTZ If you are a wireless wonk like me, you have been following the story of how the FCC has been deciding upon the rules for its upcoming spectrum auction. Thanks to some horrendous lobbying by cell phone carriers, Google, and a host of others, FCC Chairman Kevin Martin and the other four commissioners have decided on how the spectrum should be sold and used. If you have not been following this whole process, you should take a look at what is going on... — Louis E. Frenzel April 9, 2007 WiMAX Progress Not Slowed By Competition WiMAX, one of many broadband wireless standards, is finally making progress—despite the massive competition. — Louis E. Frenzel December 4, 2006 Good News About Ultra Wideband The good news is that ultra wideband (UWB) wireless is finally here. The bad news is...well, I can’t think of any bad news. UWB chip vendors finally have working silicon. Now they are announcing their FCC approvals and WiMedia certification and registrations, as well as identifying some initial customers. Looks like we will actually be seeing some real UWB wireless products this coming year. — Louis E. Frenzel December 4, 2006 Dual-Mode Handsets Dead On Arrival? With so many manufacturers making dual-mode cell phones, you would think this was a hot market. It is not. In fact, NO cellular carrier offers these handsets and probably will not, as they compete directly with their own businesses. — Louis E. Frenzel November 8, 2006 A Bent Piece Of Metal As wireless devices have continued to move to higher and higher frequencies, antennas thankfully have gotten smaller. Now instead of the "whip" antenna that used to be a common sight on cordless phones, cell phones, and other wireless devices, antennas are typically totally internal. If you see any vestige of an antenna on a product, it is a small protrusion at most. But that does not make it any less important. — Louis E. Frenzel August 3, 2006 Wasting Away In A World Without Wireless As I was trying to think of a topic to write about this month, my mind wandered off into contemplating what this world would be like without wireless. A heavy duty, "what if" brain exercise for sure. Maybe discussing, or even thinking about, something that is not real is a huge waste of words, but it does make you appreciate what wireless has given us. If you work in wireless as I do, we should all demand more respect in the future. — Louis E. Frenzel March 2005 An Old Favorite Has A New Twist Lately, it seems like everyone who is connected to the wireless-handset market is concerned with convergence. Previously, such convergence meant having one device that could function as both a phone and an e-mail/wireless-Internet device. In other words, people thought the trend would be toward carrying a single device rather than a cell phone, Blackberry, and more. Yet only a small fragment of the market—mostly... — Nancy Friedrich February 2005 Billing Issues Leave Users Unsatisfied A few months ago, my husband and I decided to purchase new cell phones. We opted to stay with our existing carrier and called to see what type of deals were available for new phones. When we found out that we were each eligible for a $150 rebate, we went to the store to compare the newest makes and models. It quickly became clear that we could choose a basic 2G phone or a full-featured phone with all of the newest bells and whistles—video capability, color display, camera, etc. There... — Nancy Friedrich January 2005 Services Put An End To Simple Times Did you ever watch any of those old, black-and-white science-fiction movies? They were so forward thinking in their depiction of technology. A spaceship crew, for instance, was often shown talking via handheld devices that were part of complex communications systems. Yet the moviemakers' imaginations only went so far, as the films always showed wired devices. As we begin 2005, the situation is the opposite: It's becoming harder to imagine a world that's not wireless. Over the past... — Nancy Friedrich December 2004 Tell Us Your Worst Design Nightmares The past few years have been tough, to say the least. Sales have dropped, cutbacks have been implemented, and staffs have been trimmed. As engineering companies have become more "streamlined," one would think that projects would run more smoothly.... — Nancy Friedrich November 2004 Wireless Rides The Cyclic Market Have you ever noticed that even though everything changes, the pattern of change seldom varies? Paradoxically, some things seem to be in constant flux while others seem to remain relatively unchanged. Take the technology markets, for instance.... — John Blyler October 2004 We're Branching Out To Serve You Better With the advent of the Internet, a multitude of new resources suddenly appeared at the engineer's fingertips. Instead of having to rely on phone calls and catalogs, engineers can now browse the web and surf information-filled design sites. In fact,... — John Blyler , et al. September 2004 Not More WLAN Alphabet Soup! Just when you thought it was safe, another 802.11 standard variation has emerged on the scene. This standard is known as 802.11n. Its intention is to enable next-generation Wi-Fi, which is capable of sustaining data throughput in excess of 100 Mbps.... — Cheryl Ajluni  prev. page
